made reversible by means of mechanism for l reversing the direction ofthe mold-board, the latter being partially rotated. upon anapproximately upright axis.

In my improved plow, two rotary `moldboards are used, one facing in theproper direction to be operative when the plow isv moved in onedirection and the other standing in proper position for action when theplow moves in the opposite direction, and each being rovided withmechanism for raising and owering `out ofand into the ground. Y r

In the accompanying drawings, Figure 1 is a plan of a plow embodying myimprovement; Fig. 2 is a side elevation; Fig.3 is a detail section onthe line 3-3 of Fig. 1; Fig. 4 is a section on the line 4 -4 of. Fig. 1;Fig. 5 is a section on the line 5-5 of Fig. 1, looking toward the right;Fig. 6 is a section on the line 6`6 ofFig. 1, looking toward the left;Fig. 7 is a detail view of a bearing plate and fixed plate by means ofwhich the disks are secured to the plow frame.

Referring to said drawings, 1 is the land wheel and 2, 2 are the furrowwheels ordinarily used in such plows. Said wheels constitute thecarrying wheels of the plow. The beam, 3, has its ends, 4, turnedlaterally, and the furrow wheels, 2,are secured to said ends by means ofcrank-form axles, 5, resting in upright bearings, 6, and havinghorizontal arms, 7, to the free ends of which are coupled horizontallinks or bars, 8, which lead to controlling levers of ordinary form andwhich are not shown in the drawings, for the reason that they are wellknown in this art` and d not relate to the present invention.

The middle of the beam, 3, is bent laterally to the same side as are theends, 4, to

form a V-shape portion, 9, and a bridge-A form piece, 10,extendshorizontally across the vopen side of said V-shape portion, andto the middle of said bridge-form piece is secured a block, 11, havingan upright aperture receiving the upright arm, 12, ofthe angle-form axlepiece, 13to which said land wheel, 1, is applied. Said arm, 12, may beheld non-rotatable in said block, 11, or it may be rotatable to alimited extent, if so desired, so that the plane of said land wheel willautomatically assume a slight inclination to an upright plane which isparallel to the line of draft. But, as such adjustability of said wheelis known in the art and does not constitute a part of the presentinvention, I deem it unnecessary to describe such construction indetail. `Within said V-shape portion, 9, is an inner bridge-piece, 14,which is parallel to the line of draft, and to the middle of saidbridge-piece, 14, is secured a block, 15, to which is hinged the innerend of a tongue, 16. To each lateral portion of the beam, 4, is applieda stop, 17, and a latch, 18, which constitute locking mechanism by meansof which the tongue may be secured lin either of two positions parallelto the line of draft. When the tongue is secured in one of saidpositions by one of said locking devices, the plow is adapted to'bedrawn in the direction of the free end of said tongue, and when saidtongue has been released and turned horizontally upon its pivot throughhalf a circle and secured by the other of said locking devices, the plowis adapted to be drawn in the opposite direction.

Two revolving mold-boards or disks, 19, 19, are applied to the outeroblique faces of the V-shape portion, 9, of the beam in such manner asto permit bodily upward and downward movement. Each such disk isjournaled in a bearing, 20, which bearing is supported by a plate, 21,and said plate is secured to an upright reciprocatory shaft 22, at theupright edge of the said plate which is the nearer the furrow wheels. Tothe outer face of the V-sha e portion of the beam is immovably aiiixe anupright 1plate, 23, having along its upright edgewhic is the nearer thefurrow wheels a iiange, 24, extending over the adjacent ed e of thebearing plate, 21. Mounted upon t e fixed plate, 23, is an uprightbearing, 25, through which rises the shaft, 22. Within the V-shapeportion of the beam is a third bridge-piece, 26, upon which Vare mountedtwo segmental racks, 27;

p and to each of such racks is applied a rack lever, v2S. Adjacent toand aXially in line with each such rack is a horizontal bearing, 29, inwhich rests the horizontal arm of a crank, 30, the inner end ot said armbeing attached rigidly to the adjacent rack lever, 28. To the outer endofthe other arm of said crank is coupled one end of a link, 3l, and saidlink rises thence and has its other end loosely coupled to theiupper endof the upright shaft, 22.

From the foregoing it will be understood that the reciprocation oteither rack lever, 28, will effect the raising and lowering of thecorresponding disk, and that by setting said rack lever in ditlerentpositions, said disk may be secured at ditterent elevations. ln theoperation of the plow, the disk which is adjacent the tongue (as thelatter is then set) is lowered sufficiently to make the desired cut,while the other of said disks is raised sutficiently to clear the groundu hile the then forward disk is making its cut. When the end of theiield is reached and the tongue is reversed for the return trip, thesepositions of the disks are reversed.

A rigid seat-post, 32, supports a seat, 33. Said post rises from theblock, l5, and is loosely surrounded by the tongue, 16, so that saidpost forms the journal for said tongue. Above said tongue a collar orsimilar stop, 34, is secured to the seat-post so as to prevent thetongue from moving upward. The upper portion ot the seat-post is bentlaterally toward the land side ot the plow and then upward, so that saidseat is at a convenient distance from the rack levers, 28. The upper endof said post has an upright journal, 35, which enters the correspondingbearing, 36, whereby the seat is made rotatable in a horizontal plane,so that said seat maybe reversed when the tongue is reversed.

The beam, 3, is rendered more rigid by means of the bridge-pieces, 10,14, and 26. The beam may be further strengthened by means of braces, 37,placed into the angles between the main portion ot the beam and the beamends, 4. The beam, said bridgepieces, and said braces, 37, togetherconstitute the frame of the plow.

When one of the disks is cutting, the ground presses it toward theadjacent portion of the beam and the adjacent 'fixed plate, 23, so thatthe bearing plate, 2l, is pressed against said iiXed plate. rllhus saiddisk retains its proper position, notwithstanding the tact that itsbearing plate is hinged on an upright axis by means of the shaft, 22,the link, 31, being coupled loosely so as to ermit a limited rotation otsaid shaft. Tiis construction leaves the disk free to trail when it isthe rear disk and is by accident low enough to be engaged by the ground.And as each disk is the rear disk during the lowing of alternate turrowsthe disks trail a ternately.
